The ISS is the largest artifical satellite orbiting Earth -- with 240ft long solar panels and a 150ft long body, its mass is over 227 tons. Being this big, and orbiting at only a 350km altitude, it can be discerned as a non-pointlike object with a normal sized telescope. If your telescope can keep up, that is. The ISS crosses the sky in about five minutes. It's usually much easier just to enjoy watching it look like a bright star crossing the sky (predictions here: Heavens-Above.com)

I have a link to a PDF of an analysis of the absorption lines here:http://www.kwasan.kyoto-u.ac.jp/~kamio/archive/spectrum/hb_1st.pdfThe sharp line just to the left of H-beta is Fe I, or unionized iron, for instance. I resized the image to match the scale on the PDF (at least how it appears on my computer); putting the two together gets you identifications of the lines in my image.It isn't perfect--on the spectrum I did a motion blur in the vertical direction to smooth out noise, but I know everything is not perfectly vertical (I think there is some curvature of field in the spectroscope, and probably in the camera lens). In addition, the hydrogen beta line is definitely not symmetrical.

It's kinda neat that you can say there's iron, nickel, chromium, cobalt, titanium, and even maybe vanadium in the sun, yes?

Michael Milligan has posted the complaint of Jose Padilla, an American, while being incarcerated without any ability to talk to his lawyer, to challenge his detention, to access any of his God-given rights at all. I was astonished to read the things done to him in the complaint. I post Milligan's emphasis in bulk.

In an effort to gain Mr. Padilla’s "dependency and trust," he was tortured for nearly the entire three years and eight months of his unlawful detention. The torture took myriad forms, each designed to cause pain, anguish, depression and, ultimately, the loss of will to live. The base ingredient in Mr. Padilla’s torture was stark isolation for a substantial portion of his captivity. For nearly two years – from June 9, 2002 until March 2, 2004, when the Department of Defense permitted Mr. Padilla to have contact with his lawyers – Mr. Padilla was in complete isolation. Even after he was permitted contact with counsel, his conditions of confinement remained essentially the same. He was kept in a unit comprising sixteen individual cells, eight on the upper level and eight on the lower level, where Mr. Padilla’s cell was located. No other cells in the unit were occupied. His cell was electronically monitored twenty-four hours a day, eliminating the need for a guard to patrol his unit. His only contact with another person was when a guard would deliver and retrieve trays of food and when the government desired to interrogate him.

His isolation, furthermore, was aggravated by the efforts of his captors to maintain complete sensory deprivation. His tiny cell – nine feet by seven feet – had no view to the outside world. The door to his cell had a window, however, it was covered by a magnetic sticker, depriving Mr. Padilla of even a view into the hallway and adjacent common areas of his unit. He was not given a clock or a watch and for most of the time of his captivity, he was unaware whether it was day or night, or what time of year or day it was.

In addition to his extreme isolation, Mr. Padilla was also viciously deprived of sleep. This sleep deprivation was achieved in a variety of ways. For a substantial period of his captivity, Mr. Padilla’s cell contained only a steel bunk with no mattress. The pain and discomfort of sleeping on a cold, steel bunk made it impossible for him to sleep. Mr. Padilla was not given a mattress until the tail end of his captivity. Mr. Padilla’s captors did not solely rely on the inhumane conditions of his living arrangements to deprive him of regular sleep. A number of ruses were employed to keep Mr. Padilla from getting necessary sleep and rest. One of the tactics his captors employed was the creation of loud noises near and around his cell to interrupt any rest Mr. Padilla could manage on his steel bunk. As Mr. Padilla was attempting to sleep, the cell doors adjacent to his cell would be electronically opened, resulting in a loud clank, only to be immediately slammed shut. Other times, his captors would bang the walls and cell bars creating loud startling noises. These disruptions would occur throughout the night and cease only in the morning, when Mr. Padilla’s interrogations would begin.

Efforts to manipulate Mr. Padilla and break his will also took the form of the denial of the few benefits he possessed in his cell. For a long time Mr. Padilla had no reading materials, access to any media, radio or television, and the only thing he possessed in his room was a mirror. The mirror was abruptly taken away, leaving Mr. Padilla with even less sensory stimulus. Also, at different points in his confinement Mr. Padilla would be given some comforts, like a pillow or a sheet, only to have them taken away arbitrarily. He was never given any regular recreation time. Often, when he was brought outside for some exercise, it was done at night, depriving Mr. Padilla of sunlight for many months at a time. The disorientation Mr. Padilla experienced due to not seeing the sun and having no view on the outside world was exacerbated by his captors’ practice of turning on extremely bright lights in his cell or imposing complete darkness for durations of twenty-four hours, or more.

Mr. Padilla’s dehumanization at the hands of his captors also took more sinister forms. Mr. Padilla was often put in stress positions for hours at a time. He would be shackled and manacled, with a belly chain, for hours in his cell. Noxious fumes would be introduced to his room causing his eyes and nose to run. The temperature of his cell would be manipulated, making his cell extremely cold for long stretches of time. Mr. Padilla was denied even the smallest, and most personal shreds of human dignity by being deprived of showering for weeks at a time, yet having to endure forced grooming at the whim of his captors.

A substantial quantum of torture endured by Mr. Padilla came at the hands of his interrogators. In an effort to disorient Mr. Padilla, his captors would deceive him about his location and who his interrogators actually were. Mr. Padilla was threatened with being forcibly removed from the United States to another country, including U.S. Naval Base at Guantanamo Bay, Cuba, where he was threatened his fate would be even worse than in the Naval Brig. He was threatened with being cut with a knife and having alcohol poured on the wounds. He was also threatened with imminent execution. He was hooded and forced to stand in stress positions for long durations of time. He was forced to endure exceedingly long interrogation sessions, without adequate sleep, wherein he would be confronted with false information, scenarios, and documents to further disorient him. Often he had to endure multiple interrogators who would scream, shake, and otherwise assault Mr. Padilla. Additionally, Mr. Padilla was given drugs against his will, believed to be some form of lysergic acid diethylamide (LSD) or phencyclidine (PCP), to act as a sort of truth serum during his interrogations.

Throughout most of the time Mr. Padilla was held captive in the Naval Brig he had no contact with the outside world. In March 2004, one year and eight months after arriving in the Naval Brig, Mr. Padilla was permitted his first contact with his attorneys. Even thereafter, although Mr. Padilla had access to counsel, and thereby some contact with the outside world, those visits were extremely limited and restricted. Significantly though, it was not until Mr. Padilla was permitted to visit with counsel that one of his attorneys, Andrew Patel, was able to provide Mr. Padilla with a copy of the Qur’an. Up until that time, for a period of almost two years, Mr. Padilla was the right to exercise his religious beliefs.

The deprivations, physical abuse, and other forms of inhumane treatment visited upon Mr. Padilla caused serious medical problems that were not adequately addressed. Apart from the psychological damage done to Mr. Padilla, there were numerous health problems brought on by the conditions of his captivity. Mr. Padilla frequently experienced cardiothoracic difficulties while sleeping, or attempting to fall asleep, including a heavy pressure on his chest and an inability to breath or move his body.

In one incident Mr. Padilla felt a burning sensation pulsing through his chest. He requested medical care but was given no relief. Toward the end of his captivity, Mr. Padilla experienced swelling and pressure in his chest and arms. He was administered an electrocardiogram, and given medication. However, Mr. Padilla ceased taking the medicine when it caused him respiratory congestion. Although Mr. Padilla was given medication in this instance, he was often denied medication for pain relief. The strain brought on by being placed in stress positions caused Mr. Padilla great discomfort and agony. Many times he requested some form of pain relief but was denied by the guards.

The cause of some of the medical problems experienced by Mr. Padilla is obvious. Being cramped in a tiny cell with little or no opportunity for recreation and enduring stress positions and shackling for hours caused great pain and discomfort. It is unclear, though, whether Mr. Padilla’s cardiothoracic problems were a symptom of the stress he endured in captivity, or a side effect from one of the drugs involuntarily induced into Mr. Padilla’s system in the Naval Brig. In either event, the strategically applied measures suffered by Mr. Padilla at the hands of the government caused him both physical and psychological pain and agony.

It is worth noting that throughout his captivity, none of the restrictive and inhumane conditions visited upon Mr. Padilla were brought on by his behavior or by any actions on his part. There were no incidents of Mr. Padilla violating any regulation of the Naval Brig or taking any aggressive action towards any of his captors. Mr. Padilla has always been peaceful and compliant with his captors. He was, and remains to the time of this filing, docile and resigned – a model detainee.

Mr. Padilla also wants to make clear that the deprivation described above did abate somewhat once counsel began negotiating with the officials of the Naval Brig for the improvements of his conditions. Toward the end of Mr. Padilla’s captivity in the Naval Brig he was provided reading materials and some other more humane treatment. However, despite some improvement in Mr. Padilla’s living conditions, the interrogations and torture continued even after the visits with counsel commenced.

In sum, many of the conditions Mr. Padilla experienced were inhumane and caused him great physical and psychological pain and anguish. Other deprivations experienced by Mr. Padilla, taken in isolation, are merely cruel and some, merely petty. However, it is important to recognize that all of the deprivations and assaults recounted above were employed in concert in a calculated manner to cause him maximum anguish. It is also extremely important to note that the torturous acts visited upon Mr. Padilla were done over the course almost the entire three years and seven months of his captivity in the Naval Brig. For most of one thousand three hundred and seven days, Mr. Padilla was tortured by the United States government without cause or justification. Mr. Padilla’s treatment at the hands of the United States government is shocking to even the most hardened conscience, and such outrageous conduct on the part of the government divests it of jurisdiction, under the Due Process clause of the Fifth Amendment, to prosecute Mr. Padilla in the instant matter.

I took three images from the raw frames available on JPL's Mars Rover web site and created a color image. They are not the fully correct colors: I used the "near-IR" (750nm) filter for red, green for green, and the UV (or short-pass 430nm) filter for blue. Opportunity Color filter IDs are from Mars Rover Pancam Filter Specs. I sharpened the image and slightly reduced the cyan content. Colors are, as you should always suspect, suspect.
